Subject: staging: lustre: ldlm: ldlm_lib: remove unneeded null test before free
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1134507ca420fadd465ebdbc4f6c5d5798d6ab87;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

staging: lustre: ldlm: ldlm_lib: remove unneeded null test before free

Kfree can cope with a null argument, so drop null tests.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@ expression ptr; @@

- if (ptr != NULL)
  kfree(ptr);
// </smpl>
